Pressure relief valve, low pressure high CFM

[potatonet]

Does anyone know where I can find a relatively inexpensive pressure relief valve capable of the following specs:

0-30 psi
600 cfm flow
either electronic or manual adjustment

I would prefer the threading to be less than 3/4" and this thing needs to be SMALL. No huge contraption, I just need a spring valve but locating one is proving to be difficult.

sorry guys, I meant to say pop off valve, or spring valve.

Valve I need needs to automatically release pressure at a preset pressure value (adjustable on the valve).

I will clarify the use of this valve:

2.5" line with 600 cfm flowing through it. not an automotive setup.

I need to retain 16 psi - 25 psi through the line (varies on use). I need a pop off valve to help me keep that pressure. after looking at how much I am trying to bleed I dont believe it needs to be 600 cfm, more like 100-200 cfm. air source is pumping 650 cfm.

sorry Im new at this kind of thing. =-/
